Hi I'm new to the site and started playing Pokemon Ruby. I was able to save using the in game feature, but unable to load the game using F2. All that happens is the screen loses its brightness. Where should I be pressing F2 at?

I can't find my save games on Pokemon Leaf Green, I press f2 and it just freezes. I'm using chrome, I saved via the in game feature and I wasn't logged in when I was playing.(I played around 13 hours so I'm really hoping someone can help me with this problem)

I saved my pokemon emerald game right before ii was about to beat Petalburg gym and after i got and tried to log back on it just randomly loaded my game as a new game. Is there any way i can access my previously saved parts of my game?
